@Stability(value=Stable)
public static interface CfnCluster.ManagedScalingPolicyProperty
extends software.amazon.jsii.JsiiSerializable

Managed scaling policy for an Amazon EMR cluster.

The policy specifies the limits for resources that can be added or terminated from a cluster. The policy only applies to the core and task nodes. The master node cannot be scaled after initial configuration.

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.emr.*;
 ManagedScalingPolicyProperty managedScalingPolicyProperty = ManagedScalingPolicyProperty.builder()
         .computeLimits(ComputeLimitsProperty.builder()
                 .maximumCapacityUnits(123)
                 .minimumCapacityUnits(123)
                 .unitType("unitType")
                 // the properties below are optional
                 .maximumCoreCapacityUnits(123)
                 .maximumOnDemandCapacityUnits(123)
                 .build())
         .build();

Method Detail

getComputeLimits

@Stability(value=Stable)
 @Nullable
default Object getComputeLimits()

The EC2 unit limits for a managed scaling policy.

The managed scaling activity of a cluster is not allowed to go above or below these limits. The limit only applies to the core and task nodes. The master node cannot be scaled after initial configuration.

builder

@Stability(value=Stable)
static CfnCluster.ManagedScalingPolicyProperty.Builder builder()

Returns:

a CfnCluster.ManagedScalingPolicyProperty.Builder of CfnCluster.ManagedScalingPolicyProperty
